RK Chain BL520ZXW-120L XW-Ring - Black Scale

RK’s ZXW series is used for both racing and general use. ZXW and RK’s Drag Racing Chain 530PRODR are each made for very different disciplines, but both share the same racing technology which provides the ultimate in high performance drive chains. ZXW features MotoGP and FIM Suzuka 8 Hour Endurance technology and has proven superiority by winning 35 first place finishes out of 39 races at the FIM Suzuki 8 Hour Endurance Race. Several features are required for an exceptionally performing endurance race chain. These include:

• Low Friction – The chain must not reduce power output from the engine
• High Tensile Strength – The chain must be able to withstand the extreme loads of race engines
• Consistency – The chain must consistently perform during the entire race duration
• Fuel Efficient – The chain must not decrease the engine’s fuel efficiency

All these features are in perfect balance in the construction of the ZXW chain. RK’s ZXW series chains are ideal for high-speed, high-horsepower performance applications, large displacement and extended swingarm machines.
